JZEQ Virus (.JZEQ File) 🔐 Decrypt & Removal Guide

The Jzeq virus, also known as a ransomware, is part of the STOP/DJVU family. This malware is notorious for file encryption and extortion. When the Jzeq virus gets into a computer system, it targets various types of files, such as documents, videos, photos, and more. It modifies the file structure and adds the “.jzeq” extension to each file, making them unusable without the decryption key.

Jzeq Virus Overview

The Jzeq virus is a malicious program that encrypts your files and forces you to pay for their restoration. This ransomware encrypts various file types. Encrypted files are identifiable by a distinct “.jzeq” extension. The files touched by ransomware become impossible to access and use.

After that, the ransomware asks for a file decryption payment in Bitcoin from its victims, ranging from $490 to $980. Typically, a ransom text file is named as “_readme.txt“.

Jzeq Ransomware operates by Salsa20 encryption algorithms to scramble the contents of the targeted files. Since Jzeq virus applies such a robust ciphering method, it becomes incredibly hard, if even possible, to pick the decryption key without cooperating with the attackers.

Once Jzeq malware finishes the encryption, it shows a ransom note to the victim, demanding a ransom payment in exchange for the decryption key. The ransom note contains instructions on the ways of making the payment and often contains threats of data loss or increased ransom amounts if the ransom is not paid within a specified timeframe.

I have created an all-encompassing list of potential solutions, advice, and approaches to remove the Jzeq malware and decrypt your files. There are situations where you can regain access to the files, while sometimes, it may be impossible.

Jzeq employs a unique key for every victim, with one exception:

The Jzeq virus is similar to other DJVU ransomware variants like Yzqe, Yzoo, Yzaq, and Ppvw. This virus encrypts a wide range of common file types and appends its distinct “.jzeq” extension to all files. For instance, a file named “1.jpg” would be altered to “1.jpg.jzeq” and “2.png” to “2.png.jzeq“.

Upon successful encryption, the virus creates a special text file named “_readme.txt” and places it in every folder containing the encrypted files. It as well adds the readme file to the desktop, so the victim will not miss the attack even without opening folders.

The image below provides a visual representation of files with the “jzeq” extension:

Encrypted Files by STOP/DJVU Ransomware

This message asking payment is for restore files via decryption key:

_readme.txt (STOP/DJVU Ransomware) – The terrifying warning demanding users to pay the ransom to decrypt the encoded data contains these annoying cautions.

Jzeq ransomware arrives as a set of tasks that are used to carry out different functions on a victim’s computer. One of the primary processes being launched is winupdate.exe, a deceptive process that displays a fake Windows update notification during the attack. Such a trick helps to convince the victim that a sudden computer slowdown is caused by a Windows update.

Meanwhile, the ransomware runs another process (which name commonly consists of 4 random characters) which initiates scanning the disk for target files and encrypting them. Next, the ransomware deletes Volume Shadow Copies from the disk by the following CMD command:

vssadmin.exe Delete Shadows /All /Quiet

Once deleted, it becomes virtually impossible to retrieve the previous computer state using System Restore Points. The problem is, ransomware operators are getting rid of any built-in Windows approaches that could assist the victim to restore files for free. In addition, the rascals modify the Windows HOSTS file by appending a list of domains to it and mapping them to the localhost IP. As a result, the victim will encounter a DNS_PROBE_FINISHED_NXDOMAIN error when accessing one of the blocked websites.

We noticed that ransomware tries to block websites that promote various how-to guides for computer users. It is obvious that by hindering specific domains, the crooks are attempting to prevent the victim from accessing relevant and helpful ransomware-attack-related information online. This malware also keeps two text files on the victim’s computer that offer particulars related to the attack – the victim’s public key and personal ID. These two files are named bowsakkdestx.txt and PersonalID.txt.

After all these changes, the malware doesn’t cease. Variants of STOP/DJVU tend to release Vidar password-stealing Trojan on compromised systems. This threat has an large list of capabilities, including:

• Stealing Steam, Telegram, Skype login / password;
• Stealing cryptocurrency wallets;
• Downloading other malware to the computer and running it;
• Stealing browser cookies, saved passwords, browsing history, and more;
• Viewing and manipulating files on victim’s computer;
• Allowing the hackers to perform other tasks on the victim’s computer remotely.

The cryptography algorithm used by DJVU/STOP virus is AES-256. So, if your data got encrypted with an online decryption key, the possibility to get your files back are quite low. Thing is, the key is unique for each victim, and brute forcing it will take exceptionally big amount of time.

Obtaining the online decryption key in any other way is also close to impossible. It is kept on a command server owned by the criminals who promote the Jzeq infection. For receiving decrypting code the payment should be $980. To obtain the payment details, the victims should contact the fraudsters by email ([email protected]).

The message by the ransomware states the following information:

How To Decrypt .jzeq Files?

The newest extensions released around the end of August 2019 after the criminals made changes. This includes Yzqe, Yzoo, Yzaq etc.

As a result of the alterations made by the criminals, STOPDecrypter is no longer backed. It has been replaced with the Emsisoft Decryptor for STOP Djvu Ransomware developed by Emsisoft.

You can download free decryption tool here: Decryptor for STOP Djvu.

1. Select folders for decryption.

   Based on the default configurations, the decryptor will by default choose the accessible directories in order to decrypt the currently available drives (the connected ones), including the network drives. Extra (optional) locations can be selected with the assistance of the “Add” button.

   Decryptors generally propose several options depending on the specific malware family. The existing possible options are displayed in the Options tab and can be activated or deactivated there. You may find a comprehensive list of the currently active Options below.

2. Click on the “Decrypt” button.

   As soon as you add all the desired locations for decryption into the list, click on the “Decrypt” button in order to initiate the decryption procedure.

   Note that the main screen may turn you to a status view, letting you know of the active process and the decryption statistics of your data:

   

   The decryptor will notify you as soon as the decryption procedure is completed. If you need the report for your personal papers, you can save it by choosing the “Save log” button. Note that it is also possible to copy it directly to your clipboard and to paste it into emails or messages here if you need to do so.

The Emsisoft Decryptor might display different messages after a failed attempt to restore your files:

✓ Error: Unable to decrypt file with ID: [your ID]

There is no corresponding decryption key in the Emsisoft decryptor’s database.

✓ No key for New Variant online ID: [your ID]

Notice: this ID appears to be an online ID, decryption is impossible

Your original files were encrypted with an online key. So no one else has the same encryption/decryption key pair. Recovery of files without paying the criminals is impossible. 🙁

✓ Result: No key for new variant offline ID: [example ID]

This ID appears be an offline ID. Decryption may be possible in the future.

An offline key was used, but files could not be restored (the offline decryption key isn’t available yet). But, receiving this message is good news for you, since it is possible to restore your files in the future. 🙂

It can take a few weeks or months until the decryption key gets found and uploaded to the decryptor. Please follow updates regarding the decryptable DJVU versions here.

✓ Remote name could not be resolved

This stands for a DNS issues. Try resetting your HOSTS file to default.

How to Restore .jzeq Files?

In some case ransomware is not doom for your files…

The Jzeq ransomware encryption mechanism is next: it encrypts every file byte-by-byte, then saves a file copy, removing (not overriding!) the initial file. Thus, the data of the file location on the physical disk is lost, but the original file is not deleted from the drive. The cell, or the sector where this file was kept, can still keep this file, but it is absent in the file system and can be overwritten by data that has been loaded to this disk after the deletion. Hence, it is possible to retrieve your files using special software.

Recovering your files with PhotoRec

PhotoRec is an free program, which is originally created for file retrieval from damaged disks, or for data recovery in case if they are unintentionally deleted. However, with time flow, this program received the ability to retrieve the files of 400 different extensions. Hence, it can be used for data recovery after the Jzeq attack.

First, you need to download this app. It is 100% free, but the developer states that there is no assurance that the files will be recovered. PhotoRec is spread in a pack with another tool of the same developer – TestDisk. The resulting archive will bear TestDisk name, but don’t worry. PhotoRec files are right inside.

To launch PhotoRec, you need to find and open “qphotorec_win.exe” file. No installation process is required – this program has all the files it need within the archive, hence, you can mount it on your USB drive, and try to help your friends/parents/anyone who has been attacked by Jzeq ransomware.

Upon the start, you will witness the screen showing you the complete list of your disks. However, this details are likely futile, because the required menu is placed a bit higher. Click this tab, then choose the disk which was attacked by ransomware.

After selecting the disk, you need to choose the destination folder for the recovered files. This menu is located at the lower part of the PhotoRec window. The best choice is to export them on USB drive or any other type of removable disk.

Then, you need to designate the file formats. This setting is located at the bottom, too. As it was mentioned, PhotoRec can retrieve the files of about 400 different formats.

Finally, you can begin files recovery by pressing the “Search” button. You will observe the screen where the findings of the scan and recovery are shown.
